Final answer:
The products of alcohol fermentation are ethanol and carbon dioxide. This biochemical process allows yeast and some bacteria to produce energy under anaerobic conditions by converting glucose into these end products.The correct answer is option A.
Step-by-step explanation:
The products of alcohol fermentation are ethanol and carbon dioxide. This process occurs when yeast and some types of bacteria break down sugars in the absence of oxygen. Glucose is first converted to pyruvic acid during glycolysis.
Then, in the fermentation process, pyruvic acid is transformed into ethanol and carbon dioxide. The overall chemical reaction for alcohol fermentation can be represented as:
glucose →→→ ethanol + carbon dioxide
Not only does this process produce ethanol and carbon dioxide, but it also regenerates NAD+ from NADH, which allows glycolysis to continue producing ATP for the cell, even in the absence of oxygen.The correct answer is option A.
